usg's tuff hide over existing paint

Jeff

Hi Guys,
I am a former sheetrocker, drywall business owner (toughest trade in residential building) turned GC back in 93 still do a lot of small stuff myself, as a builder am most critical of drywallers, however in cost estimating I do allow for touchup and trade repairs.

I am considering using USG tuff hide over existing ceilings painted flat white,
almost every screwed revealed itself in the two years since customer moved in. There is a vast amount of morning sunlight both direct and reflective off the bay. the screws have been reset and three coated and butt joints had to be re-coated.

according to usg this product will produce a level five finish and will not be necessary to apply a finish coat, seems like a no brainer! There is about four thousand sq ft to repair.

The walls in this house are painted Ben Moores Arizona Tan my customer would like to have a sprayed on finish to match an old plaster finish as close as possible to finish paint color.

Any info would be appreciated

FOR THOSE ABOUT

Tuff Hide is thick you will need the right sprayer/tip. Just finished 400 sheets new construction. Had to redo a ceiling over flat white paint because lack of adequate temp causing the product to fisheye. Make sure surface/air temp is at least 60. The product will lay down. It's cheaper then the Builders Solution $50 vs. $75 per 5 gal. We used the Mark V with a 5/21 tip at 3000 PSI and cross hatched the spray pattern horizontally then immediatley vertically with great results enough pigment where we did not need to paint. What about the walls?
